# Eve Renderer Parity

Parity is currently uneven by design. The shared surface contract is forming,
but the browser reference is the first renderer that can be used as a practical
comparison oracle.

See [runtime-app-parity-roadmap.md](./runtime-app-parity-roadmap.md) for the
generic Eve app plan across web, Fensalir Direct2D, iOS/UIKit, and
Android/Kotlin. Repixelizer is the first style-parity target.

## Current State

| Renderer | Status | Proof | Gap |
| --- | --- | --- | --- |
| Web reference | First generic app target | `web/` renders live VoidBot and fixture surfaces | Needs provider picker, Repixelizer fixture, visual regression fixtures, and command round-trip tests |
| iOS / UIKit | Native proof | Renders Odin's fullscreen interface wall from `surface.root`, generic provider trees, and a custom VoidBot cockpit with avatar images | Needs provider picker, Repixelizer style token lowering, and visual parity fixtures |
| Android / Kotlin | Device-edge proof | APK builds and shows broker/sensor status | Needs provider picker, full surface tree rendering, style token lowering, asset image lowering, and command controls |
| Fensalir Direct2D | Documented landing zone | Existing `AquariumUiDocument` and `DirectWriteOverlay` path | Needs adapter from Eve surface document to `AquariumUiDocument` and DirectWrite/Direct2D token lowering |
| Flutter | Candidate shared native path | Not installed locally | Needs toolchain and client scaffold |

## Spawned Surfaces

The browser reference runner currently exposes hardcoded fixture/live tabs:

- `VoidBot Live`: connects to Mimir's `/eve/deck` broker and opens
  `voidbot.swarm`.
- `Fensalir Direct2D`: loads `web/fixtures/fensalir-client-surface.json`, a
  recorded surface describing the Direct2D client lowering path.
- `Sai VN Surface`: loads `web/fixtures/sai-vn-surface.json`.
- `Huginn .cc`: compiles `web/fixtures/huginn-cc-surface.eve`.
- `Reactive DSL`: compiles `web/fixtures/reactive-composition.eve`.

Those tabs are temporary probes. The runtime app target is a provider picker
fed by `gamecult.eve.provider_advertisement.v1`, with fixtures represented as
local advertisements.
